What is MID?
The Measuring Instruments Directive (MID)
was introduced by the European Commission
to promote free trade of measuring
instruments throughout Europe.
Any meter used for billing of electricity, must be either MID
approved or approved under UK national legislation. Meters
already installed, that were approved under UK national
legislation prior to October 2006 may remain installed
indefinitely, as long as they are measuring accurately. Any new
meter manufactured and approved after October 2006 must
be approved under the MID regulations. In the UK, the MID is
applicable for loads up to 100kW. After October 2016 every
new meter installed for billing must be MID approved. It is a
criminal offence to use a non approved meter for billing.
